The Leughenaer tower was built in 1548 as part of the Dunkerque defense fortifications. In 1825, a light was installed on the tower, which served as the main lighthouse until the Dunkerque Lighthouse became operational in 1843. From 1845, the Leughenaer Light served to mark the channel between the jetties, along with the original light on the west jetty (Dunkerque Jetée Ouest), until it was discontinued in the 1960s.
